Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a selective printing roll device for indicating the type of mail item in an automatic postmarking machine.

With an automatic postmarking machine, a prepayment stamp consisting of a charge stamp with a place of return and date indication, as well as a sender stamp or an advertising stamp, is printed on the mail piece or on the paper tape wrapped around the mail piece.

In addition to these various stamps, the present invention also provides
It is an object of the present invention to provide one selection printing roll device for displaying various mail types. In this case, the space requirement must also be small.

This object has been achieved by the configuration of the present invention as set forth in claim 1. Advantageous embodiments thereof are indicated in the following claims.

The invention will now be explained with reference to the embodiment shown in the drawings: In the illustrated embodiment, the printing roll 7 is a printing roll adjustable in five stages for five types of mail, including printed matter, express mail, registered mail, etc. It has four types of parcels, and the fifth type is for ordinary mail and has no special markings. Instead of one common printing roll with five such adjustment possibilities, any number of characters may be used, which is limited by the size of the printing roll circumference. Furthermore, the type may be arranged on the printing roll in a replaceable manner. The type sets representing each type are arranged diagonally upward to the right or downward to the right, rather than on a line parallel to the axis of the printing roll 7, and are therefore printed in a diagonal layout, making them easy to stand out.

The printing roll 7 is arranged in a printing drum 12 of an automatic postmarking machine, the bearing pins of the printing roll shaft 9 being arranged in both side plates 10 of the printing drum 12. A first transmission shaft 1 is arranged eccentrically with respect to the not-illustrated rotational axis of the printing drum 12, that is, it is immovably supported by a bearing pin 8 in one side plate 10 of the printing drum 12 and the other side plate. The first transmission shaft 1 rotatably supports one adjustment gear 2 having external teeth and internal teeth on its circumferential surface, and does not rotate itself. This adjustment gear 2 is driven via a drive gear 13 either clockwise or counterclockwise. A second transmission shaft 4 is rotatably supported in one hole in the first transmission shaft 1, and the second transmission shaft 4 has a gear 3 at one end.
At the other end, each gear is provided with a sector 5, which gearwheel 3 and sector 5 are rigidly connected to the second transmission shaft 4, for example by a frictional connection. The gear 3 is guided in a notch in the first transmission shaft 1,
This provides positioning against axial displacements with corresponding tolerances. The teeth of the gear 3 mesh with the internal teeth of the adjustment gear 2. The rotation of the adjusting gear 2 on the stationary first transmission shaft 1 causes a pivoting movement of the sector 5 in the same direction. This sector 5 is engaged with a printing roll gear 6 and is accompanied by rotation of the printing roll 7. A locking spring 11, which engages in a corresponding notch in the print roll shaft 9, holds the print roll 7 in the correct position for the selected character.

Printing roll 7 that selectively prints the type of mail item
are co-located in the printing drum 12 alongside a prepaid stamp mechanism consisting of a toll stamp with place of return and date indications, although the prepaid stamp mechanism is not shown in the drawing for clarity. The printing drum 12 forms part of an automatic postmarking machine, and is rotationally driven by its own rotating shaft (not shown). By this rotational movement of the printing drum 12, the envelope is transferred, for example, with not only the charge and sender's name printed, but also the type of the envelope printed. Assuming that the printing drum 12 rotates in the direction of the arrow, envelopes are fed from the lower left and discharged from the lower right at the bottom of the printing drum 12 as seen in the figure (see dashed lines and arrows). Type printing is applied to the side, above, or below the charge print in relation to the size of the charge print.

In the figure, following the printing of the charge stamp including the place of return and date display, the type is implicitly printed by the printing roll 7 in diagonal letters to make it more noticeable. There is. In the drawings, for clarity, the printing roll 7 is shown in a position before printing, and the printing type is shown in a state where it has just been printed.

The adjustment of the printing roll 7 takes place by correspondingly turning the adjusting drive gear 13 circumscribing the adjusting gear 2 in either direction in an adjusting manner. The driving gear 13 is rotated directly by hand or via a lever mechanism. If the drive gear 13 is rotated, for example, clockwise when viewed from the drawing plane, the adjustment gear 2, and therefore the gear 3 and the sector 5 will rotate counterclockwise, and the printing roll gear 6 will further rotate clockwise. . As soon as the printing roll 7 is adjusted to the desired type as the printing roll gear 6 rotates, the locking spring 11 is inserted into a notch (not shown) on the printing roll shaft 9.
Insert and lock in place. The drive gear is then shifted out of its meshing position with the adjusting gear 2 (the position shown). As the printing drum 12 is rotated by the drive of a rotating shaft (not shown), the entire selection printing roll devices 1 to 9 and 11 rotate while being held in position by the locking spring 11.
